Context

Wualt (also referred to as Armotrix in earlier project docs) builds a wristband that reads a tanker driver’s HRV, EDA, SpO2 and skin temperature and turns it into a Fatigue Score from 0 to 100. The client is a national petroleum distributor, and the named end user is the DGM who owns regulatory reporting and signs the monthly PESO safety submission. This is the client’s Enterprise surface, one of five surfaces planned for the wider Wualt FleetOps product, and the one that had to convince the client the platform was worth trusting with a safety-critical workflow.

Problem

The client’s existing Permit-to-Work check only captures a driver’s state at the moment of departure. It misses everything that happens in the 6 to 16 hours after that, on stretches of Tamil Nadu highway where fatigue-related incidents actually happen. The dashboard had to make a continuous physiological signal legible and actionable to one DGM, while proving to a regulator (PESO) and a privacy team that raw biometric data never left the wristband. It also had to stop looking like a generic ops dashboard: the first pass read as dense and telemetry-heavy, closer to SAP than to something a DGM would trust as premium-engineered.

Approach

Eight cross-linked screens were built around one DGM’s actual day: Overview, Contractor Compliance, PTW Audit Trail, Network Safety Report, Route Risk Index, Terminals, Reports and Exports, and Settings. A single running narrative, one contractor (Meridian Fuels) sliding into an amber compliance score and one driver’s PTW breaching red mid-journey on the corridor, was threaded through all eight screens so the system could be reviewed as one continuous case rather than eight disconnected mockups. The aesthetic went through a real pivot during the work: early passes used a dense mono-coded terminal look, but the direction that shipped moved to a Linear-style dark palette (bg #08090a, single cyan accent #7170ff) with glass surfaces and Plex Sans as the default body font, mono reserved only for identifiers and codes. Iteration ran in visible passes: fixing accent-color overuse, building a real three-tier button hierarchy, replacing a disappearing sidebar with a VS Code-style icon rail, and propagating every fix to all eight files so no screen was left behind.

Outcome

All 8 screens for the client’s Enterprise surface are built as self-contained HTML mockups (no build step), fully cross-linked, with a consistent design system and a 6-tier responsive cascade. Per the project’s own tracker, this is 1 of 5 planned Wualt FleetOps surfaces; the other four (Driver App, Contractor Supervisor Dashboard, Contractor Top Management App, Armotrix Internal Ops) were not yet designed as of this snapshot. No claims are made here about live deployment, real user testing, or the client’s actual sign-off status beyond what the project docs describe (a design deliverable, not a shipped or client-approved product).
